Abstract

The invention discloses a graphene reinforced epoxy resin anticorrosion coating which is characterized by being prepared from the following raw materials: epoxy resin E51, butadiene rubber, n-hexane, maleic anhydride, dicumyl peroxide, tetrahydrofuran, methanol, p-xylylenediamine, dibutyltin dilaurate, graphene oxide, aniline, hydrochloric acid, an ammonium persulfate solution, octaphenyl polyoxyethyiene, carboxymethyl cellulose, a proper amount of acetone and a proper amount of deionized water. The graphene reinforced epoxy resin anticorrosion coating disclosed by the invention has the advantages of being good in salt water resistance, good in corrosion resistance, free of toxin, good in environmental friendliness and the like.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a graphene-enhanced epoxy resin anti-corrosion coating and a preparation method thereof. Background technique [0002] There are many types of anti-corrosion coatings, and the common ones are epoxy resin coatings, polyurethane coatings, and inorganic-rich coatings. When using, it is necessary to select the appropriate anti-corrosion coating according to different corrosion environments. At the same time, according to different corrosion environments, it can also be developed by analyzing the role of different film-forming base materials, solvents, fillers and additives in anti-corrosion coatings. Targeted anti-corrosion coating products. Among them, the cured epoxy resin has the advantages of good mechanical properties, good chemical stability, good electrical insulation, low shrinkage, good temperature resistance, easy processing and low price. The disadvantages of high cross-linki...
